Removed node_module, yarn.lock and node-cache. But no success.

This error is not project specific. If i run yarn, node or npm anywhere in my system I'm getting above error. Is my node and yarn package corrupted?

Have you installed the dependencies ? `npm install` if you have the dependency in your package.json, or `npm install ts-node` if not — Seblor, Feb 20 '20 at 10:43
@Seblor I have ts-node as my dev-dependency. i added moment in my package and to install i run yarn install. Then it gave above error.Before running yarn install everything was working fine. — Himanshu Shekhar, Feb 20 '20 at 10:47
I'm not getting how it corrupted my entire system.. This issue is now not project specific. — Himanshu Shekhar, Feb 20 '20 at 10:48
Have you tried reinstalling node ? I suggest using [`nvm`](https://github.com/nvm-sh/nvm) for managing node installs — Seblor, Feb 20 '20 at 10:50

Solved Issue by checking NODE_OPTIONS

Run echo %NODE_OPTIONS% and got ts-node/register.

So, to remove ts-node/register run setx NODE_OPTIONS ""

After this node,npm and yarn are working properly.

Try following command:

Step 1 : remove node_modules and files and package-lock.json

Then run following command to install dependencies:

Step 2: $ rm -rf node_modules package-lock.json && npm install && npm start

Finally, run your package by following command:

npm start
